Checking of Fuel Pump Relay
Trouble-shooting: Nominal Value: Cause of Fault: (If nominal value is not attained)
· Ignition OFF > 11 V · Connecting line from fuel pump relay Remove fuel pump relay K 58 from K 58 Ter. 30 to vehicle voltage interrupted. frame. - Plug connection defective: Measure voltage at fuel pump X 11 Ter. 5(KADETT-E/ASTRA/BELMONT) pump relay K 58 Ter. 30 X 11 Ter. 1(CORSA/NOVA)
· Short-circuit fuel pump relay Fuel pump ON · Connecting line from fuel pump relay frame K 58 between terminals Ter. 30 K 58 Ter. 87 to fuel pump interrupted. and Ter. 87. - Plug connection defective: X 11 Ter. 1 or X 6 Ter. 14 (KADETT-E/AST/BEL.) X 11 Ter. 3 (CORSA/NOVA) or - Fuse defective: F 16 (KADETT-E/ASTRA/BELMONT) F 1 (CORSA/NOVA) or - Connecting line from fuel pump to ground interrupted or - Fuel pump defective.
· Remove short circuit between terminals < 3 W · Connecting line from relay frame K 58 Ter. 30 and Ter. 87. Ter. 85 to ground interrupted. Check connecting line from relay frame K 58 Ter. 85 to ground for passage way with multimeter (200 W)
· Ignition OFF > 11 V · Connecting line from fuel pump relay Measure voltage at control 3 s later K 58 Ter. 86 to control unit K 100 Ter. A 1 unit plug K 100 Ter. A 1 with < 2 V has short circuit to ground or multimeter (20V/DC) - Control unit defective Ignition ON
· Ignition OFF > 11 V · Connecting line from fuel pump relay Measure voltage at fuel pump 3 s later K 58 Ter. 86 to control unit K 100 Ter. A 1 relay K 58 Ter. 86 with multimeter < 2 V interrupted. (20V/DC) Ignition ON
· Ignition OFF > 11 V, · Relay defective or Insert fuel pump relay. fuel pump ON - Control unit defective Measure voltage at fuel 3 s later pump relay K 58 Ter. 86 with < 2 V, multimeter (20V/DC) fuel pump OFF Ignition ON
